The authoring system generates an input embedding vector that represents the search input in a latent space using a machine learning model trained on training data to generate embedding vectors in the latent space. A candidate embedding vector included in a group of candidate embedding vectors is identified based on a distance between the input embedding vector and the candidate embedding vector in the latent space. The authoring system generates an indication of a search output associated with the digital form for display in a user interface based on the candidate embedding vector.

BACKGROUND

A digital form is authored by a user interacting with an input device (e.g., a mouse, a stylus, a touchscreen, etc.) relative to a user interface to add form elements to the digital form such as fields and fragments. The fields are capable of receiving information, e.g., textboxes, and the fragments are groups of fields which are frequently reused across multiple forms, e.g., a “Contact Details” block. Once the digital form is authored, the form is usable to collect and store information from many different domains.

SUMMARY

Techniques and systems for assistive digital form authoring are described. In a first example, a computing device implements an authoring system to receive input data describing a search input associated with a digital form. In a second example, the authoring system receives the input data describing a form element included in the digital form.

In the first example, the authoring system generates an input embedding vector that represents the search input in a latent space using a machine learning model trained on training data to generate embedding vectors in the latent space. A candidate embedding vector included in a group of candidate embedding vectors is identified based on a distance between the input embedding vector and the candidate embedding vector in the latent space. The authoring system generates an indication of a search output associated with the digital form for display in a user interface based on the candidate embedding vector.

In the second example, the authoring system represents the digital form as a sequence of elements. In this example, the authoring system identifies an additional form element based on the sequence of elements and the form element using a collaborative filtering model trained using additional training data to identify form elements for digital forms. An indication of the additional form element is generated for display in the user interface.

DETAILED DESCRIPTION Overview

In order to author a digital form using conventional systems, a user interacts with an input device (e.g., a stylus, a touchscreen, a mouse, a keyboard, etc.) relative to an authoring interface to identify user interface components of the authoring interface that represent particular fields and fragments. For instance, the user manually identifies the user interface components through several interactions with various menus and submenus of the authoring interface. The user then manipulates the input device relative to authoring interface to add the identified user interface components to an editing panel of the authoring interface which causes the particular fields and fragments represented by the user interface components to be added to the digital form. However, manually identifying the user interface components via the various menus and submenus of the authoring interface is time consuming and inefficient.

To overcome these limitations, techniques and systems for assistive digital form authoring are described. In an example, a computing device implements an authoring system to receive input data describing an interaction relative to a digital form being authored in the authoring interface. In some examples, the interaction is a search input associated with the digital form. In other examples, the interaction is an inclusion of a form element in the digital form.

In an example in which the authoring system receives the input data as describing the search input associated with the digital form, the authoring system generates an input embedding vector that represents the search input in a latent space using a machine learning model trained on training data to generate embedding vectors in the latent space. In one example, the machine learning model includes a Bidirectional Encoder Representations from Transformers model. The authoring system compares the input embedding vector to candidate embedding vectors included in a group of candidate embedding vectors described by embeddings data.

For example, each of the candidate embedding vectors represents a candidate search output in the latent space and the authoring system generates the candidate embedding vectors by processing the candidate search outputs using the trained machine learning model. The authoring system compares the embedding vectors by computing similarities or distances between the input embedding vector and the candidate embedding vectors in the latent space. In an example, the authoring system computes the similarities as cosine similarities and identifies a set of candidate embedding vectors (e.g., a top 5, a top 10, a top 15, etc.) from the group such that candidate embedding vectors included in the set have a highest similarity with the input embedding vector.

The authoring system generates indications of candidate search outputs represented by the candidate embedding vectors included in the set for display in the authoring interface. In one example, the authoring system generates the indications as user interface components. In this example, the user manipulates the input device relative to the authoring interface to interact with a particular one of the user interface components which adds a corresponding form element to the digital form being authored in the user interface.

In an example in which the authoring system receives the input data as describing a form element included in the digital form (e.g., the corresponding form element of the previous example), the authoring system represents the digital form as a sequence of elements. Elements included in the sequence of elements represent form elements (e.g., fields and/or fragments) that are included in the digital form. For example, the form elements were previously added to the digital form being authored in the authoring interface and the form element is added to the digital form more recently than the form elements.

The authoring system processes the sequence of elements and the form element using a collaborative filtering model based on form data. For instance, the form data describes databases of thousands of digital forms. The collaborative filtering model processes the sequence of elements including the form element and the form data to identify a set of additional form elements. In an example, additional form elements included in the set have not been previously included in the digital form being authored in the authoring interface. In one example, the collaborative filtering model identifies the additional form elements included in the set based on a number of cooccurrences between the form element and the additional form elements in the digital forms described by the form data. In another example, the collaborative filtering model identifies the additional form elements included in the set based on a distance or a closeness between cooccurrences of the form element and ones of the additional form elements in the digital forms described by the form data.

The authoring system generates indications of the additional form elements for display in the authoring interface. For example, the authoring system generates the indications as additional user interface components for display in the authoring interface. The user manipulates the input device relative to the authoring interface to interact with a particular one of the additional user interface components which adds a corresponding form element to the digital form being authored in the user interface.

By generating and displaying indications of candidate search outputs and additional form elements relative to the authoring interface in this manner, the user avoids multiple interactions with various menus and submenus of the authoring interface to identify user interface components usable to add particular form elements to the digital form. This increases efficiency of digital form authoring relative to the time consuming conventional systems. Additionally, computational costs of identifying the candidate search outputs and the additional form elements are minimal such that the described systems are implementable in network-based applications which are capable of identifying candidate search outputs and/or additional form elements in substantially real time.

Term Examples

As used herein, the term “machine learning model” refers to a computer representation that is tunable (e.g., trainable) based on inputs to approximate unknown functions. By way of example, the term “machine learning model” includes a model that utilizes algorithms to learn from, and make predictions on, known data by analyzing the known data to learn to generate outputs that reflect patterns and attributes of the known data. According to various implementations, such a machine learning model uses supervised learning, semi-supervised learning, unsupervised learning, reinforcement learning, and/or transfer learning. For example, the machine learning model is capable of including, but is not limited to, clustering, decision trees, support vector machines, linear regression, logistic regression, Bayesian networks, random forest learning, dimensionality reduction algorithms, boosting algorithms, artificial neural networks (e.g., fully-connected neural networks, deep convolutional neural networks, or recurrent neural networks), deep learning, etc. By way of example, a machine learning model makes high-level abstractions in data by generating data-driven predictions or decisions from the known input data.

As used herein, the term “embedding vector” refers to a numerical representation of an intent or a natural language search query in a latent space. By way of example, embedding vectors for intents/queries and embedding vectors for other intents/queries that are generated by a trained machine learning model are comparable to infer similarities and differences between the intents/queries and the other intents/queries.

In the following discussion, an example environment is first described that employs examples of techniques described herein. Example procedures are also described which are performable in the example environment and other environments. Consequently, performance of the example procedures is not limited to the example environment and the example environment is not limited to performance of the example procedures.

Example Environment

FIG. 1 is an illustration of an environment 100 in an example implementation that is operable to employ digital systems and techniques as described herein. The illustrated environment 100 includes a computing device 102 connected to a network 104. The computing device 102 is configurable as a desktop computer, a laptop computer, a mobile device (e.g., assuming a handheld configuration such as a tablet or mobile phone), and so forth. Thus, the computing device 102 is capable of ranging from a full resource device with substantial memory and processor resources (e.g., personal computers, game consoles) to a low-resource device with limited memory and/or processing resources (e.g., mobile devices). In some examples, the computing device 102 is representative of a plurality of different devices such as multiple servers utilized to perform operations “over the cloud.”

The illustrated environment 100 also includes a display device 106 that is communicatively coupled to the computing device 102 via a wired or a wireless connection. A variety of device configurations are usable to implement the computing device 102 and/or the display device 106. For instance, the computing device 102 includes a storage device 108 and an authoring module 110. The authoring module 110 is illustrated as having, receiving, and/or transmitting input data 112.

As shown, the input data 112 describes a form element 114 and a search input 116. The form element 114 is a name field and the search input 116 is a natural language search query for “Personal details.” For example, a user generates the input data 112 via interaction with an input device (e.g., a mouse, a stylus, a keyboard, a touchscreen, etc.) relative to an authoring interface 118 which is displayed in a user interface 120 of the display device 106. In this example, the user manipulates the input device relative to the authoring interface 118 to move a user interface component 122 into an editing panel 124 in order to generate the input data 112 as describing the form element 114. Similarly, the user generates the input data 112 as describing the search input 116 by manipulating the input device to enter the natural language search query in a search field 126 of the authoring interface 118.

Consider an example in which the user has limited experience in digital form authoring and the authoring module 110 includes a collaborative filtering model which is capable of accessing form data 128. The form data 128 describes a database of digital forms (or multiple databases of digital forms) which includes a variety of different forms such as government forms, corporate forms, forms authored by the user, forms authored by other users, etc. In some examples, these various forms are tagged or labeled with intent information (e.g., page intent, section intent, etc.) and/or natural language descriptions of fields/fragments included in the forms. For example, the authoring module 110 implements the collaborative filtering model to process the input data 112 and the form data 128 to identify an additional form element 130 which is displayed relative to the authoring interface 118.

To do so in one example, the authoring module 110 flattens a digital form being authored in the authoring interface 118 into a sequence of elements (e.g., with particular entries for container elements) and processes the sequence of elements along with the form element 114 using the collaborative filtering model to identify the additional form element 130 based on the form data 128. Elements included in the sequence of elements correspond to form elements included in the digital form being authored in the authoring interface 118, and the authoring module 110 identifies the additional form element 130 based at least partially on a current state of the digital form being authored in the authoring interface 118. The additional form element 130 is not included in the digital form before being identified by the authoring module 110. In the illustrated example, the digital form being authored is blank and the authoring module 110 identifies the additional form element 130 based on the form element 114 and the form data 128. For instance, the additional form element 130 is statistically common in digital forms described by the form data 128.

In one example, the authoring module 110 implements the collaborative filtering model to identify the additional form element 130 based on a number of cooccurrences of the form element 114 and the additional form element 130 in the digital forms described by the form data 128. In another example, the authoring module 110 uses the collaborative filtering model to identify the additional form element 130 based on a closeness of or a distance between the form element 114 and the additional form element 130 in the digital forms described by the form data 128. In the illustrated example, the authoring module 110 identifies the additional form element 130 as a state field which is statistically likely to follow the name field of the form element 114 based on the form data 128. In an example in which the form element 114 is a fragment (a reusable group of fields such as an address block or legal text), the authoring module 110 identifies the additional form element 130 as a fragment which is statistically likely to follow the form element 114 in the digital forms described by the form data 128.

Consider an example in which the authoring module 110 includes a machine learning model such as a Bidirectional Encoder Representations from Transformers model trained on training data to generate embedding vectors for search inputs and search outputs in a latent space. In this example, the authoring module 110 trains the machine learning model on training data describing pairs of search inputs and corresponding search outputs described by the form data 128 such that an embedding vector generated for a search input is separated by a relatively small distance from an embedding vector generated for a corresponding search output in the latent space. For example, the embedding vector generated for the search input is separated by a relatively large distance in the latent space from an embedding vector generated for a different search output which corresponds to a different search input. In this example, the authoring module 110 trains the machine learning model on the training data using a negative log-likelihood loss.

In one example, the authoring module 110 identifies candidate search outputs for search inputs based on the form data 128. The authoring module 110 implements or causes the trained machine learning model to generate a candidate embedding vector in the latent space for each of the identified candidate search outputs. For instance, the authoring module 110 generates embeddings data 132 as describing the candidate embedding vectors and corresponding candidate search outputs which the authoring module 110 stores on the storage device 108. When the authoring module 110 receives the input data 112 describing the search input 116, the authoring module 110 implements the trained machine learning model to generate an input embedding vector that represents the search input 116 in the latent space.

The authoring module 110 then computes distances between the input embedding vector and the candidate embedding vectors described by the embeddings data 132. For example, the authoring module 110 computes the distances based on a cosine similarity between the input embedding vector that represents the search input 116 and the candidate embedding vectors that represent the candidate search outputs. In this example, the authoring module 110 identifies a candidate embedding vector described by the embeddings data 132 as being separated from the input embedding vector by a smallest distance in the latent space (e.g., a greatest similarity). The identified candidate embedding vector corresponds to a search output 134 which is displayed relative to the authoring interface 118.

As shown, the additional form element 130 is the state field and the search output 134 is a date of birth field. In one example, the search output 134 is also a form element. By precomputing the candidate embedding vectors described by the embeddings data 132 and identifying the search output 134 based on the distances in the latent space, the authoring module 110 is capable of implementing systems for digital form authoring via the network 104. This is because computing the distances in the latent space is a computationally efficient process which is performable in substantially real time in some examples.

The user interacts with the input device relative to the authoring interface 118 to add the additional form element 130 and/or the search output 134 to the digital form being authored in the authoring interface 118. In the example in which the user has limited experience in digital form authoring, identifying the additional form element 130 and the search output 134 is informative based on thousands of digital forms described by the form data 128. However, in an example in which the user has substantial experience in digital form authoring, identifying the additional form element 130 and the search output 134 increases efficiency of digital form authoring by avoiding multiple steps and interactions with the authoring interface 118 to manually identify the additional form element 130 and the search output 134.

FIG. 2 depicts a system 200 in an example implementation showing operation of an authoring module 110. The authoring module 110 is illustrated to include a filtering module 202, an embedding module 204, and a display module 206. As shown, the authoring module 110 receives the input data 112, the form data 128, and the embeddings data 132 as inputs.

FIGS. 3A, 3B, 3C, and 3D illustrate examples of generating indications of form elements based on form elements included in a digital form. FIG. 3A illustrates a representation 300 of a blank digital form being authored in the authoring interface 118. FIG. 3B illustrates a representation 302 of a first form element added to the digital form. FIG. 3C illustrates a representation 304 of a second form element added to the digital form. FIG. 3D illustrates a representation 306 of a third form element added to the digital form.

With reference to FIG. 3A, the filtering module 202 receives the input data 112 as describing the blank digital form being authored in the authoring interface 118. The filtering module 202 also receives the form data 128 describing databases of thousands of different digital forms which are tagged or labeled with intent information (e.g., page intent, section intent, etc.) and/or natural language descriptions of fields/fragments included in the forms. In the representation 300, the user has not yet interacted with an input device (e.g., a stylus, a mouse, a keyboard, a microphone, a touchscreen, etc.) relative to the authoring interface 118 to add any form elements to the digital form being authored in the authoring interface 118.

The filtering module 202 processes the input data 112 and the form data 128 to identify statistically common form elements that are included in the digital forms described by the form data 128 such as a top N form elements. In some examples, the filtering module 202 identifies the form elements based on fields/fragments that have previously been included in digital forms authored by the user or a similar user. In an example in which the input data 112 describes a title of the digital form being authored in the authoring interface 118, the filtering module 202 is capable of processing the form data 128 to identify the form elements as being included in digital forms having semantically similar titles to the title.

For example, the filtering module 202 identifies a first set of form elements and generates element data 208 as describing the first set of form elements. The display module 206 receives and processes the element data 208 to generate and display user interface components 308-332 in the authoring interface 118. The user interface components 308-332 each correspond to an identified form element included in the first set of form elements described by the element data 208. As shown, each of the user interface components 308-332 is usable to add a field/fragment to the digital form being authored in the authoring interface 118. For instance, user interface component 308 adds a “Date” field, user interface component 310 adds a “Sex” field, user interface component 312 adds an “Address” field; user interface component 314 adds a “Name” field, user interface component 316 adds a “City” field, user interface component 318 adds a “Phone” field, user interface component 320 adds a “Zip Code” field, user interface component 322 adds a “State” field, user interface component 324 adds an “Occupation” field, user interface component 326 adds a “First Name” field, user interface component 328 adds a “Surname” field, user interface component 330 adds a “Marital Status” field, and user interface component 332 adds an “Age” field to the digital form being authored in the authoring interface 118.

In an example, the user interacts with the input device relative to the authoring interface 118 to move the user interface component 326 into the editing panel 124. As shown in FIG. 3B, adding the user interface component 326 to the editing panel 124 adds a first name field 334 to the digital form. The filtering module 202 receives the input data 112 as describing the first name field 334 included in the digital form being authored in the authoring interface 118. For example, the filtering module 202 includes the collaborative filtering model, and the filtering module 202 implements the collaborative filtering model to process the input data 112 and the form data 128 to identify a second set of form elements.

In an example, this is representable as:

$A = \begin{bmatrix} 1 & \ldots & 1 \\  \vdots & \ddots & \vdots \\ 1 & \ldots & a_{ij} \end{bmatrix}$ where: A is a sparse matrix and a_(ij) is 1 if an i^(th) digital form described by the form data 128 has form element j. ũ=[1 . . . ] where: ũ is a digital form vector that indicates which form elements are present in the digital form being authored in the authoring interface 118.

d = [ …e^((n_(i) − k)r)…]k ∈ (0, n_(i)] where: d is a drop-off factor that emphasizes recently authored form elements in the digital form being authored in the authoring interface 118; n_(i) represents a number of form elements included in the digital form; and k is used to keep track of how recently a corresponding form element was authored. Form Similarity: Aũ ^(T) ·d R=αR ₁₀+(1−α)R _(all) where: R₁₀ is a weighted element score of a top 10 similar digital forms; R_(all) is a weighted element score for all similar forms; α is a hyperparameter; and R is a score for a form element that indicates a likelihood that the form element is present in digital forms similar to the digital form being authored in the authoring interface 118 without consideration of nearness or closeness of form elements in the digital forms. R _(ũ) =[ . . . p _(k) . . . ] where: R_(ũ) is an element probability score and p_(k) captures a probability of expecting element k in an immediate neighborhood given ũ. R _(overall) =βR _(ũ)+(1−β)R predictions=k argmax R _(overall) where: R_(overall) is an overall element score and β is a hyperparameter.

The filtering module 202 identifies the second set of form elements using the collaborative filtering model trained on the form data 128 as training data, and the filtering module 202 generates the element data 208 as describing the second set of form elements. For example, the training data describes form elements included together in digital forms of a collection of digital forms described by the form data 128. The display module 206 receives and processes the element data 208 to generate and display user interface component 336, user interface component 338, the user interface component 322, the user interface component 316, user interface component 340, the user interface component 320, the user interface component 312, user interface component 342, user interface component 344, the user interface component 328, user interface component 346, and the user interface component 308 in the authoring interface 118. For example, the user interface component 336 adds a “Last Name” field, the user interface component 338 adds a “Middle Name” field, the user interface component 340 adds a “Country” field, the user interface component 342 adds a “Gender” field, the user interface component 344 adds a “Date of Birth” field, and the user interface component 346 adds a “Pin Code” field to the digital form being authored in the authoring interface 118.

The user further interacts with the input device relative to the authoring interface 118 to move the user interface component 336 into the editing panel 124. As illustrated in FIG. 3C, adding the user interface component 336 to the editing panel 124 adds a last name field 348 to the digital form. For instance, the filtering module 202 receives the input data 112 as describing the last name field 348 and also the first name field 334. The filtering module 202 implements the trained collaborative filtering model to identify a third set of form elements by processing the input data 112 and the form data 128. For example, the filtering module 202 generates the element data 208 as describing the third set of form elements. In this example, the display module 206 receives and processes the element data 208 to generate and display the user interface component 322, the user interface component 316, the user interface component 338, the user interface component 320, user interface component 350, user interface component 352, user interface component 354, the user interface component 308, the user interface component 342, user interface component 356, and the user interface component 344 in the authoring interface 118. The user interface component 350 adds a “Middle Name” field, the user interface component 352 adds an “E-mail Address” field, the user interface component 354 adds a “Social Security Number” field, and the user interface component 356 adds a “Suffix” field to the digital form being authored in the authoring interface 118.

For instance, the user interacts with the input device relative to the authoring interface 118 to move the user interface component 316 into the editing panel 124 of the authoring interface 118. This interaction adds a city field 358 to the digital form which is shown in the representation 306 of FIG. 3D. In an example, the filtering module 202 receives the input data 112 as describing the city field 358 as the most recently added form element to the digital form being authored in the authoring interface 118. In this example, the input data 112 also describes the first name field 334 and the last name field 348.

The filtering module 202 flattens the digital form into a sequence of the first name field 334, the last name field 348, and the city field 358 and processes the sequence along with the form data 128 using the trained collaborative filtering model to identify a fourth set of form elements. For example, the filtering module 202 generates the element data 208 as describing the fourth set of form elements, and the display module 206 receives and processes the element data 208 to generate and display the user interface component 322, the user interface component 320, the user interface component 312, the user interface component 350, the user interface component 342, user interface component 360, the user interface component 344, user interface component 362, and the user interface component 330 in the authoring interface. As illustrated in FIG. 3D, the user interface component 360 is usable to add a “Home Phone” field to the digital form and the user interface component 362 is usable to add a “Work Phone” field to the digital form.

For example, the user interacts with the input device relative to the authoring interface 118 to add an additional form element to the digital form and/or to enter a search query in the search field 126. In the example in which the user enters the search query in the search field 126, the embedding module 204 receives the input data 112 as describing a search input based on the search query. FIG. 4 illustrates a representation 400 of a machine learning model. The embedding module 204 includes the machine learning model in an example. As shown in the example illustrated in FIG. 4 , the machine learning model includes a Bidirectional Encoder Representations from Transformers model.

In an example, the machine learning model's architecture is representable as: f(x)=w _(o) x+w ₁ B ₁(x) . . . +w _(k) B _(K)(x) where: B_(i)(x) represents an output of the i^(th) transformer layer (with K total layers) and w_(i) represents learnable weights of the i^(th) transformer layer.

The embedding module 204 trains the machine learning model on training data describing pairs of search inputs and corresponding candidate search outputs extracted from the form data 128. In one example, the embedding module 204 defines a similarity between embedding vectors generated for pairs of the search inputs and candidate search outputs using the machine learning model as a cosine similarity which is representable as:

${{sim}\left( {q_{i},c_{j}} \right)} = \frac{\left\langle {{f\left( q_{i} \right)},{f\left( c_{j} \right)}} \right\rangle}{❘{❘{{f\left( q_{i} \right)}{{❘❘} \cdot {❘{❘{f\left( c_{j} \right)}❘}❘}}}}}$ where: q_(i) represents a search input and c_(j) represents a candidate search output.

Although similarity between embedding vectors generated for pairs of the search inputs and candidate search outputs using the machine learning model is described as a cosine similarity, it is to be appreciated that other definitions of similarity are usable in other examples. For example, the embedding module 204 is capable of defining similarity between embedding vectors in the latent space based on Manhattan distances, Hamming distances, Euclidian distances, Minkowski distances, and so forth.

In order to maximize similarity between matching pairs of search inputs and outputs (q_(i), c_(i)) and to minimize similarity between non-matching pairs of search inputs and outputs (q_(i), c_(j≠i)), the embedding module 204 trains the machine learning model on the training data by maximizing a negative log likelihood which is representable as:

$L = {- {\log\left( \frac{e^{si{m({q_{i,}c_{i}})}}}{{\sum}_{j \neq i}e^{si{m({q_{i,}c_{j}})}}} \right)}}$

As described above, the authoring module 110 precomputes a candidate embedding vector for each of the candidate search outputs extracted from the form data 128 using the trained machine learning model and generates the embeddings data 132 describing the candidate embedding vectors. As shown in FIG. 4 , the embedding module 204 receives the input data 112 describing a search input q 402, and the embedding module 204 processes the search input q 402 using the trained machine learning model to generate an input embedding vector f(q) 404 which represents the search input q 402 in a latent space. For example, the embedding module 204 identifies a set of candidate search outputs c by computing similarities sim(q, c) 406 between the input embedding vector f(q) 404 and the candidate embedding vectors described by the embeddings data 132. In this example, the set of candidate search outputs c is based on a number of the candidate embedding vectors described by the embeddings data 132 having a highest similarity sim(q, c) 406. For instance, the number is a top 5, a top 10, a top 15, and so forth.

The display module 206 receives and processes the candidate data 210 to generate and display an indication 528 of the fourth set of candidate search outputs. For example, the user interacts with the input device relative to the indication 528 and adds the fourth set of candidate search outputs to the digital form being authored in the authoring interface 118.

Generally, such modules include routines, programs, objects, elements, components, data structures, and so forth that perform particular tasks or implement particular abstract data types. The terms “module,” “functionality,” and “component” as used herein generally represent software, firmware, hardware, or a combination thereof. The features of the techniques described herein are platform-independent, meaning that the techniques are implementable on a variety of commercial computing platforms having a variety of processors.

Implementations of the described modules and techniques are storable on or transmitted across some form of computer-readable media. For example, the computer-readable media includes a variety of media that is accessible to the computing device 1002. By way of example, and not limitation, computer-readable media includes “computer-readable storage media” and “computer-readable signal media.”

“Computer-readable storage media” refers to media and/or devices that enable persistent and/or non-transitory storage of information in contrast to mere signal transmission, carrier waves, or signals per se. Thus, computer-readable storage media refers to non-signal bearing media. The computer-readable storage media includes hardware such as volatile and non-volatile, removable and non-removable media and/or storage devices implemented in a method or technology suitable for storage of information such as computer readable instructions, data structures, program modules, logic elements/circuits, or other data. Examples of computer-readable storage media include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, hard disks, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other storage device, tangible media, or article of manufacture suitable to store the desired information and which are accessible to a computer.

“Computer-readable signal media” refers to a signal-bearing medium that is configured to transmit instructions to the hardware of the computing device 1002, such as via a network. Signal media typically embodies computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as carrier waves, data signals, or other transport mechanism. Signal media also include any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared, and other wireless media.

As previously described, hardware elements 1010 and computer-readable media 1006 are representative of modules, programmable device logic and/or fixed device logic implemented in a hardware form that is employable in some embodiments to implement at least some aspects of the techniques described herein, such as to perform one or more instructions. Hardware includes components of an integrated circuit or on-chip system, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a complex programmable logic device (CPLD), and other implementations in silicon or other hardware. In this context, hardware operates as a processing device that performs program tasks defined by instructions and/or logic embodied by the hardware as well as a hardware utilized to store instructions for execution, e.g., the computer-readable storage media described previously.

Combinations of the foregoing are also employable to implement various techniques described herein. Accordingly, software, hardware, or executable modules are implementable as one or more instructions and/or logic embodied on some form of computer-readable storage media and/or by one or more hardware elements 1010. For example, the computing device 1002 is configured to implement particular instructions and/or functions corresponding to the software and/or hardware modules. Accordingly, implementation of a module that is executable by the computing device 1002 as software is achieved at least partially in hardware, e.g., through use of computer-readable storage media and/or hardware elements 1010 of the processing system 1004. The instructions and/or functions are executable/operable by one or more articles of manufacture (for example, one or more computing devices 1002 and/or processing systems 1004) to implement techniques, modules, and examples described herein.

The techniques described herein are supportable by various configurations of the computing device 1002 and are not limited to the specific examples of the techniques described herein. This functionality is also implementable entirely or partially through use of a distributed system, such as over a “cloud” 1014 as described below.

The cloud 1014 includes and/or is representative of a platform 1016 for resources 1018. The platform 1016 abstracts underlying functionality of hardware (e.g., servers) and software resources of the cloud 1014. For example, the resources 1018 include applications and/or data that are utilized while computer processing is executed on servers that are remote from the computing device 1002. In some examples, the resources 1018 also include services provided over the Internet and/or through a subscriber network, such as a cellular or Wi-Fi network.

The platform 1016 abstracts the resources 1018 and functions to connect the computing device 1002 with other computing devices. In some examples, the platform 1016 also serves to abstract scaling of resources to provide a corresponding level of scale to encountered demand for the resources that are implemented via the platform. Accordingly, in an interconnected device embodiment, implementation of functionality described herein is distributable throughout the system 1000. For example, the functionality is implementable in part on the computing device 1002 as well as via the platform 1016 that abstracts the functionality of the cloud 1014.
